Lie-down massager

Abstract

A lie-down massager comprises a frame having an elongated top panel with an elongated opening, a rider below the top panel, a guide member movably engaged between the frame and the rider to enable the rider to make a horizontal reciprocation relative to the frame, a lifter moving vertically relative to the rider, and a roller gear engaged to the rider. The roller gear is engaged to a vertical rack gear in an opening of an engagement body extending from the lifter so the roller gear rotation enables the lifter to make a vertical reciprocation. Massage bumps attached to the top portion of the lifter move vertically and/or horizontally along the elongated top opening of the elongated top panel of the frame by the lifter and the rider.

1. A lie-down massager, comprising:
 a) a base frame having an elongated top panel, wherein an elongated top opening is formed centrally and lengthwisely through the elongated top panel; 
 b) a rider provided below the elongated top panel of the base frame, wherein a rider opening is formed vertically through the rider to define an inner periphery of the rider; 
 c) a guide member movably engaged between the base frame and the rider so as to enable the rider to make a horizontally reciprocal movement relative to the base frame; 
 d) a first roller gear engaged to and powered by a first motor, wherein the first motor is fixed to the rider; 
 e) a lifter having a top portion and a bottom portion, wherein an engagement body downwardly extends from the bottom portion of the lifter, wherein a vertically elongated body opening is formed through the engagement body to define vertical walls in the engagement body, wherein one of the vertical walls is configured to a vertical rack gear so that the first roller gear is rollably engaged to the vertical rack gear, whereby the roller gear rotation by the first motor enables the lifter to make a vertically reciprocal movement through the rider opening while the engagement body is movably propped by the inner periphery of the rider; 
 f) massage bumps attached to the top portion of the lifter and moving vertically and/or horizontally along the elongated top opening of the elongated top panel of the base frame; and 
 g) a pad covering the massage bumps and the elongated top opening of the base frame.

 b) rider provided below the elongated top panel and having rider guide rollers on each side thereof, wherein the rider guide rollers are rollably engaged to the base frame to guide a horizontally reciprocal movement of the rider; 
 c) a roller gear engaged to and powered by a motor, wherein the motor is fixed to the rider; 
 d) a pair of pulleys linked by a rope and respectively mounted in a front end portion and a rear end portion of the base frame, wherein a predetermined portion of the rope is fixedly attached to the rider so that the pulley rotation enables the rider to generate a horizontally reciprocal movement of the rider; 
 e) a pair of roller coasters parallel to each other, wherein the roller coasters are attached to the base frame and above the rider guide rollers, wherein the roller coasters each have a substantially waved top surface;
